The 39-year-old rapper – who cancelled the remaining dates of his Saint Pablo Tour before being hospitalised last week for exhaustion and sleep deprivation – has previously been able to bounce back from a difficult period in his life, but has found it harder to cope this time around when he was on tour without his partner by his side, especially after she was held at gunpoint in Paris, France, earlier this year.

Speaking about the ‘Famous’ rapper – who is known for his erratic rants on stage - a source told PEOPLE:

“In the past, he snapped back quickly. This has been going on for years. In the past when Kanye seemed to struggle, no one took it too seriously. The attitude was more like it was just Kanye being Kanye .

“Things would go back to normal. This time is much different.

“Without having Kim by his side during the tour as planned, Kanye wasn’t able to snap back. Kim being absent because of her own struggles seems to be why things are different with Kanye this time.”

Although the musician – who has three-year-old daughter North and 11-month-old son Saint with Kim – has remained in the Ronald Regan UCLA Medical Centre in Los Angeles, California, for over one week, he is slowly starting to feel like his usual self.

Speaking previously, another insider said: “[Kanye’s] starting to feel more like himself.

“He understands that getting help at the hospital was necessary.

“He is resting and getting help. They are taking it day by day.”

Meanwhile, the Keeping Up With the Kardashians star is solely concentrating on her husband, who is her main “priority” at the moment.

A source close to the raven-haired beauty said: “Kim is focused on Kanye right now and making sure her family is getting all the care and attention that’s needed.
